Yesterday night while looking in for something in a box in a remote corner of my appartment when I found in a purse containing 5 French coins depicting Napelon III on it, the dates on them are 1853, 1854, 1855, 1856 and 1864. There is also a 10 centimes coin that dates back from 1893. I also found 3 coins, one 5 Francs from 1945, one 2 Francs from 1943 and one 1 Franc from 1942, the strange thing is that those last 3 coins are VERY light.

Does anyone have any idea about the value of those, or could anyone point me in the right direction?

Here you go. I hope they are worth a lot for you. I found a bunch of 1800s US silver dollars my dad had collected while going through his things after he passed away. Most weren't very rare (yet), but fun to see. Should make a hell of a collection for my grand-children. Good luck!! Let us know how it turns out. I'm curious.

BTW, I'm guessing the WWII era coins were light because the steel or copper was rationed for the war effort.

Thanks Jetservice! I surfed a bit on the site you suggested and I did found the Napoleon III coins unfortunately they don't have any estimations for it. I'll try to get in touch with a coin collector and see if I can get an estimation. Here's a photo of what they look like

Mine are similar except they are not marked as Deux Centime but as Dix Centime

Finally there is this one that is similar to mine except have the color faded.
